Elaina's questions allowed her to fully verify the guy before her about the seeds and their legitimacy. A good florist would always recommend flowers that are easy to grow if they are asked what plants or flowers are easy to grow. Those who only seek profit will start recommending pretty and eye-catching flowers that are sometimes expensive and are not worth the money most of the time due to how costly it is to take care of, or sometimes just not possible to grow due to the climate or they are not in season.
Since the florist before her was honest and recommended newbie flowers, Elaina asked for seeds that they sell for flowers and bought a few for each season. It might not be profitable but decorating the farm with some new colors using the flowers would be a good idea to improve the image of the place. Besides, it is good for the eyes to have and it can increase the beauty of the place little by little.
